One of the comic highlights of Sport Relief 2014 was Kylie Minogue singing Especially For You, her 1988 hit duet with Jason Donovan. But she was singing with David Walliams.

David did his best to look – and sound – like Jason Donovan and the audience cheered him on.

But the audience cheered louder when Jason himself came out singing.

Kylie skipped over to Jason in full voice – but Jason wasn’t there to re-create their famous duet.

Jason wanted to sing with David. It didn’t look pretty, or sound pretty, but it was pretty funny.
